The radios are \u201c<a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/it-networks\/2020\/10\/23\/us-army-makes-breakthroughs-on-future-network-tools\/\" target=_blank>very, very difficult to jam<\/a>,\u201d according to Dan Duvak, chief of the C5ISR Center\u2019s Radio Frequency Communications division.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The new radios are able to detect and evade interference, as well as operate on reduced power, Duvak said. Radios from each company were among the most promising capabilities at the C5ISR Center\u2019s <a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/it-networks\/2020\/10\/23\/us-army-makes-breakthroughs-on-future-network-tools\/\" target=_blank>Network Modernization Experiment<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe\u2019re pretty cognizant that if we just use our legacy system [and] send energy out in all directions, you know, we\u2019re not very efficient with our power and batteries, from dismounts and things like that,\u201d Duvak told C4ISRNET in an interview earlier this year. \u201cBut also, the adversary is going to have that capability to detect us. And as soon as they detect our radio transmissions, that\u2019s a bad place to be.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To help prevent that scenario, the Army worked started working with commercial vendors in 2019 to strengthen its radios\u2019 resiliency. The project is part of the Army\u2019s effort to modernize its tactical network by delivering new tools, known as capability sets, every two years. Capability set \u201921, which was delivered to soldiers this year, focused on filling immediate tactical network gaps.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Persistent Systems and Silvus radios are targeted for capability set \u201923, which focuses on increasing network resiliency and improving bandwidth. The Army expect to use the radios at the mid-tier, allowing soldiers in a company to communicate back to a brigade or battalion level that may be a far distance away.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The radios use several techniques to avoid interference and jamming. While working with the C5ISR Center, Persistent Systems strengthened radio transmission security by improving the robustness of its waveform, Duvak said. The advanced capabilities office took the radio to its electronic warfare lab and tested different adversarial jamming techniques on the radio to see how it performed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe\u2019ve been able to build out the types of attacks into the hundreds, varying all the types of things that get varied per jamming technique,\u201d said Eric Stern, vice president of engineering and operations at Persistent Systems. \u201cWe have built new detection and mitigation electronic protection measures, adapted those, and built them into the firmware to maximize performance.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A critical feature of the Persistent Systems radio is that the resiliency capabilities are added through a firmware update, meaning the Army can upgrade all the radios it has bought from the company. Plus, the update is free, adding major cost savings, Duvak added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Silvus radio, meanwhile, used advanced interference cancellation algorithms and frequency switching to avoid adversarial jamming. The company and the Army are excited about power control features on Silvus radio that minimize the amount of energy the radios give off in the field, helping avoid detection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt\u2019s a way of automatically throttling back the power of your system to minimize the [radio frequency] footprint,\u201d said Jimi Henderson, a Silvus vice president. \u201cAnd even in a dynamic mobile scenario where nodes are moving around, it\u2019s intended to always use the minimum power necessary to maintain a given reliability.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Duvak said that the radios are particularly useful for robotic systems in the future that need low latency and high bandwidth to send video and other large data files to soldiers, particularly if they are streaming live video. The radios from the two companies are far more capable than current models, he said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIf you have a manned vehicle controlling an unmanned vehicle, the unmanned vehicle is going to be sending live video feeds back so you can drive it right and you can control it,\u201d Duvak said. \u201cIt\u2019s also going to be collecting a lot of sensor data &#8230; of what the battlespace looks like and sending that back for situational awareness. So there\u2019s a lot of data coming back from that robotic platform.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Army made major strides with two vendors to develop radios that are
